Specification of Letters Patent.
Patented Sept. 24, 1907.
Application filed Februarv 14,1907- Serial No. 357,310-
.70 all whom it may concern:
Be it known that we, CHARLES W. RmNonnL and WILLIAM M. HENDERSON, citizens of the United States, and residents of Harrisburg, Dauphin county, State of Pennsylvania, have invented certain new and useful Improvements in Frogs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which Figure 1 is a plan view. Fig. 2 is a side elevation. Figs. 3, 4, 5, 6, 7 and 8 are respectively sections on the lines aa, bb, c-c, d-d, e@, and f-f, Fig. 1.
This invention relates to improvements in railroad frogs of the type in which the frog center-that is, the portion of the frog over which the wheel tread passes in moving from one track to the other-is formed from a hard metal insert piece suitably secured to the wing and stock rails.
The object of my invention is to provide such a frog that shall be stronger, more elastic, and more easy riding than the frogs of this type heretofore in use.
To these ends the invention consists in securing said hard metal center to the wing and stock rails by means of bolts passing therethrough adjacent the heel of the frog, and away from the crossing point of the track; and the intermediate portion of said center piece being secured to said rails by-means of clamps embracing said rails and center piece held therebetween, as hereinafter fully set forth.
1, are the usual point rails which, in this instance terminate some distance to the rear of the point of the frog, as seen in Fig. 1.
2, are the stock rails forming the throat of the frog in the usual manner, and which stock rails are bent outwardly at 3, opposite the point of the frog, and having the inner sides of their heads cut away to form recesses in which are fitted the sides, 4, of a hard metal insert piece, 5; which insert piece is also provided with the point portion, 6, whose rear end, 7, extends some distance to the rear of and between the ends of the point rails 1, forming a filling block th erebetween, whose head portion is on the same level with the head portions of said point rails, which head portions are cut to fit the sides of said extension 7 as seen in Fig. 1. The rear end of the extension 7 is downwardly beveled at 8, Figs. 1 and 8 to constitute a pick-up for false flanges of guttered wheels that may be passing along either of the point-rails, 1, thereby lifting said wheels to the level of the rail heads. Said hard metal insert or center piece, 5, is provided with the usual flange-ways or grooves, 9, between said point, 6, and the sides, 4; the inner edges of which sides, 4, being in the same plane as that of the inner sides of the heads of the rails, 2, and the sides of the points, 6, being in the same plane as the sides of the convergent point rails, 1.
The rear portions of the rails, 2, constitute the usual wings of the frog. The under surface or foot of the center piece, 5, rests upon the foot flanges of the rails,
2 and is supported thereby, the side portions of said center piece lying contiguous to thewebs and cut away portions of said rails, 2; said center piece being thereby fitted into the space between said rails, 2. Forward of the head-forming side portions, 4, of the center piece, 5, said center piece is provided with an extension, 10, which constitutes a filling and spacing block between said rails, 2, adjacent the throat of the frog. Passing through this extension, 1.0, and also through the webs of the rails, 2, and through reinforcing straps, 11, lying contiguous the outer portion of the web of said rails, are bolts, 12, for securing said extension, 8, to said rails, 2. Passing through the wing portions, 13, of the stock rails, 2, and through the filling blocks, 14, the point rails, 2, and the insert piece, 5, are bolts, 15, which secure said several parts in suitable relation, and passing through the point= rails, 1, and the rear end extension, 7, of said insert piece, 5, is a bolt, 16, for securing said rear extension in place to the point rails. Intermediate of said end extensions, 7 and 10, of the center piece, the structure is devoid of other bolts for securing the same together, and is held together at this intermediate portion by means of suitable clamping devices, (two in number, in this instance) preferably of the following construc tion:Secured respectively to the straps, 1]., in this instance by rivets, 17, are lugs, 18 and 18 011 laterally opposite sides of the structure; the lug 18 having an inclined outer surface adapted to be engaged by the corresponding inner surface of an upwardly extending arm, 19, of a yoke bar, 20, whose horizontal limb, 21, extends beneath and contiguous the foot flanges of the rails, 2, and whose. other end is provided with a second upwardly turned extending arm, 22, whose inner surface is inclined, as seen in Fig. 3 and 5; the outer surface of the lug, 18, being inclined substantially parallel to said inner surface of said arm. A split wedge key, 23, is driven home between the inner inclined surfaces of said arm and said lug 18, thereby securely clamping the parts together.
In order to prevent longitudinal movement of the clamping yoke, 20, along the rails, 2, and thereby loosening of the clamp, I would usually provide the rails, 2, with straps, 24, that engage the said clamping yoke.
By the above described construction I am able to do away with the use of bolts at the portion of the frog where the greatest strains are exerted, thereby producing a frog in which the metal at andadjacent the point is not weakened, and also the frog is more elastic and easy riding than frogs of the prior art. Also the beveled free end of the extension'7 of the hard metal piece, 5, between the point rails, 1, serves as a pick-up, as hereinbefore mentioned, to lift the false flanges of guttered wheels to the level of the trackway, and to carry the same thereafter until the crossing is completed upon the upper surface of the hard metal insert piece.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a railway frog or crossing, the combination, with the stock-rails and point-rails, of the hard-metal insert piece fitted thereto, the bolts passing through said insert piece adjacent the ends thereof and securing the same to said rails, together with the clamps embracing said stock-rails and insert piece together, substantially as and for the purpose set forth.
2. In a railway frog or crossing, the combination, with the stock-rails recessed opposite the frog point and the point-rails terminating some distance to the rear of the point, of the hard-metal insert piece having the portions fitted to said recesses in the stock-rails and having also the point-forming portion in line with and extending from said point-rails, said insert piece being also provided with the lilling block extension at the throat of the frog, together with the bolts passing through said filling block extension and securing said stock-rails and insert piece together, and the bolts securing said stock-rails, pointrails and insert piece together to the rear of the point, and the clamps embracing and securing the said parts together intermediate of said bolts, the crossing portion of said frog being held together by said clamps and devoid of bolts, substantially as and for the purpose set forth.
3. In a railway frog or crossing, the combination, with the stock-rails and point-rails, of the hardmetal insert piece secured to said stock and point-rails, and having head-forming portions fitted to the heads of said stockrails and the point portion iitted to and constituting an extension of said pointa'ails, said point portion having a rearward extension between said point-rails and whose upper surface is in substantially the same plane as the heads of said rails, the extreme rear end of said extension being downwardly beveled, substantially as and for the purpose set forth.
In testimony whereof, we have hereunto aflixed our signature.
